A series of (1,2,4)triazole[4,3-a]pyridine (TZP) derivatives have been designed and synthesized. Compound 8d was identified as having the most potent inhibitory activity on NO release in response to lipopolysaccharide (LPS) stimulation and inhibition of the migration induced by MCP-1 protein on RAW264.7 macrophages. Based on the screening data, an immunofluorescence assay and a real-time qPCR assay
已经设计和合成了一系列的(1,2,4)三唑[4,3-a]吡啶(TZP)衍生物。化合物8d被鉴定为对脂多糖(LPS)刺激具有最有效的抑制NO释放的活性,并抑制RAW264.7巨噬细胞上MCP-1蛋白诱导的迁移。基于筛选数据,进行了免疫荧光测定和实时qPCR测定,表明化合物8d通过伴刀豆球蛋白A(Con A)诱导的RAW264.7巨噬细胞抑制了NF-κBp65易位和炎性基因的表达。更重要的是8d还通过在小鼠自身免疫性肝炎(AIH)模型中下调血浆丙氨酸转氨酶(ALT),天冬氨酸转氨酶(AST)和炎性浸润的水平来缓解Con A诱导的肝炎。此外,流式细胞仪(FCM)数据表明化合物8d抑制了Con A诱导的小鼠肝脏中MDSC的积累。这些发现增加了化合物8d可能用作治疗AIH的潜在药物的可能性。
